Structured Thinking About Semantic Search

Following a March 15 Wall Street Journal article, “Google
Gives Search a Refresh,” the topic of semantic search has again become a hot-button issue for SEOs and webmasters. In that article, author Amir Efrati refers to coming changes across Google
results pages, largely derived from enhancements in its core semantic search capabilities, as “among the biggest in the company’s history and could affect millions of websites that rely on
Google’s current page-ranking results.”

If this “new” news is to be believed, then Google appears primed to make good on its promise to better understand both the Web
and the intent communicated by its user base through the queries entered. But is this really news?

Semantic search, which according to Wikipedia is the process through which search
technologies “improve accuracy by understanding searcher intent and the contextual meaning of terms as they appear in the searchable dataspace,” has been around for a while. Even over the
course of the past year, Google has been assigning semantic meaning to content items that have been marked up with the microdata format advocated by schema.org. Recently, Danny Sullivan wrote an
extensive piece on Google’s history with semantic search, and how this latest news appears to be little more than Google PR at work.

So while this may not be an earth-shattering
announcement, it does warrant investigation because Google has brought attention to it. Is there a bigger story here than meets the eye?

Google Knowledge Graph

Beyond
schema, which is a Webmaster’s tool to communicate semantic instructions to the engines, Google is building what it calls the Knowledge Graph, a collection of information sources that help
discern a user’s specified intent with each individual query, even providing for answers directly on the search engine results page where warranted.

In the healthcare space (my new
playground), Google “Symptom Search” is a great example of the Knowledge Graph in action. Enter into Google any symptom you may be experiencing (for example, “headache”), and
Google will pull data from the Knowledge Graph to direct you to possible health conditions. The traditional ten blue links have been deemphasized in favor of possible answers to the user’s
direct question. These types of interactions appear to be the future of search -- scary territory for SEOs who are accustomed to keyword-level optimization practices.

Is SEO
“Dead”?

Every few months a new article is written proclaiming the death of SEO. In fact, it happens so frequently that it’s become something of an online meme within
the SEO community. It’s easy to dismiss those pieces as largely hyperbole at work, but one caught my attention as being very timely and applicable to SEO in a Knowledge Graph environment. With
“The Rise of Content Strategy – What To Do About Google Killing SEO,”
James Mathewson teed up the challenges SEOs now face with semantic search:

“How do SEOs traditionally optimize pages? By advising their clients to put keywords in strategic places on a
page. When Google goes to semantic search, it won’t be as much about keywords at all, but on the meaning of the words you use. This might be the biggest SEO killer of all. If tuning our content
for keywords our users care about is no longer an effective strategy, what is left for SEOs?”

Mathewson goes on to advocate for a new flavor of SEO practitioner, the “content
strategist.” I agree completely with that view, and see three things that SEOs need to do right away in order to prepare for a semantically driven future in search:

1) Become a
content strategist – technical on- and off-page factors will continue to see a decline in importance. The most compelling and desirable content will win.

2) Answer questions
through content – keyword research will take center stage, and new software applications will undoubtedly be introduced that look to mine intent from raw keyword clusters. Understanding
intent will become crucial during this research phase, because content will need to be crafted to specifically answer the questions posed through user queries.

3)
Rally around standards like schema – a legitimate Knowledge Graph may one day render schema obsolete and unnecessary, but it’s the best we have to work with
today. And an early adopter opportunity still exists in every industry vertical. By employing schema today, you will become better positioned for semantic search 1.0 and will be at the forefront when
future enhancements are introduced.

This has taken quite a while to trickle down to reach the public. Google abandoned everything but semantic indexing with the Mayday update, May 2010.

Matt Cutts was emphatic enough to state that it was not going to be changed or reversed.

While the micro data is a small factor, and I have to say "small" as it is something that can be used inappropriately, the relevance between search phrase and search term is the key factor with display factors guiding the value. Google says text size and position are factors.

>Enter into Google any symptom you may be experiencing (for example, “headache”), and Google will pull data from the Knowledge Graph to direct you to possible health conditions. The traditional ten blue links have been deemphasized in favor of possible answers to the user’s direct question.

I do not see anything like this and I used FF IE and Chrome. I see a standard page of blue links with descriptions and URLs.

Google has been going towards a "reading", (as a human would see it), in their indexing efforts. They try to have their algos take their cues from the visual presentation, and in this medium, text size, position and decoration are most important.

The better your link pool is in relation to your information silos, the better your authority.

CTR and bounce rates are of high importance.

Off page factors such as linking HAVE declined in importance, PR is now a stand alone metric predicated on relevance and not a purely mathematical formula.The only area of offpage that has increased is the Social Media "citation", re-tweet, Likes, and G+1 votes.

On page factors will continue to be refined.

Beware of schema as it does not affect the visual display but is a code "modifier" and can be used inappropriately.
